<p>The OpenMP Fortran runtime library routines are provided both in
a form of two Fortran modules, named <code>OMP_LIB</code> and
<code>OMP_LIB_KINDS</code>, and in a form of a Fortran <code>include</code> file named
<samp>omp_lib.h</samp>. The procedures provided by <code>OMP_LIB</code> can be found
in the <a href="http://gcc.gnu.org/onlinedocs/libgomp/index.html#Top">Introduction</a> in <cite>GNU Offloading and Multi
Processing Runtime Library</cite> manual,
the named constants defined in the modules are listed
below.
</p>
<p>For details refer to the actual
<a href="https://www.openmp.org/wp-content/uploads/openmp-4.5.pdf">OpenMP Application Program Interface v4.5</a> and
<a href="https://www.openmp.org/wp-content/uploads/OpenMP-API-Specification-5.0.pdf">OpenMP Application Program Interface v5.0</a>.
